If you have more than one child, you have probably experienced your share of sibling disagreements. They may seem minor enough now, but the sibling relationship can become so battered, it eventually dissolves. Siblings are going to disagree. How you help them handle their conflicts is critical.
Perhaps even more important is teaching them how to apologize to each other properly for offenses. Apologies are meant to begin repairing relationships, but most apologies do more harm to the relationship than good. If you’ve ever had someone do something hateful towards you and then apologize with, “I’m sorry if I did anything to hurt your feelings,” you understand the problem.
